Other objects will appear from the.

' disclosure herein.

According to the invention, briefly stated, there is employed in connection with the radiator cap a condensing chamber of special construction'in'which a fan is turned by an externally mounted wind Wheel, said fan tending to draw cooling air into. said chamber and agitate the, mixture of air and vapors g to condense the "vapors rising from the radiator sothat they may return to the body of the .cooling liquid.

The invention is embodied in the example herein shown and described,'thefeatures of p v ber 7 by the operationof the fan 12.

. novelty being finally claimed. In the accompanying drawing V Figure 1 is a view in side elevation of the invention.

Fig. 2 is a vertical'sectionof the same on a radiator with some parts in full. 7 Fig. 3 is a'horizontalflsection of the device as on the line III III Fig.2 looking down. In the views 5 designates the body of the radiator cap which is internally threaded toscrew onto the water-supply-neck of the ra- 'diatoras usual and as indicated in Fig. 2.

Connected with the top wall of the cap are two upwardly extending tubes 6, 6, on the upperends of which is achamber 7 made of two parts threaded together so thatthey can be separated at wilL, Around the ring near the top of the chamber 7 is a series of holes 7?. Connected with'the bottom of the chamber 7 between the tubes 6, 6, is a cup or chamber-8 forming a downward extensionof thechamher 7. Said'chamber is shown'as' connected with a tube 6 by'perforations at 8 The cup or chamber 8 is spaced from thecap and to that extent increasesthe-cooling surfaces of the structure. Extending centrally upward from below the cap is a small tube 9 having in its upper end a'bearing 10in which is steppedthe conical point of a shaft 11. The upperend of the tube 9 is provided with'a number of perforations 9 Fixed on said shaft 11 within the chamber 7 is a fan fitting on the upper endoftheusual overflow and fixed o nialii breonflor said shaft above the chamber'is a windwheelylf adapted to beijturned by the wind, either that; naturally created or that artificially caused by the movement of the [vehicle as when driven, g l

The lower endof the tube-9 is bulged as shown at 9* to receive afunnel 13 of soft rubber or other suitable material said funnel pipe 14 just below the water'supply opening; of the radiator. I

- The operation can bedescrib'edfas follows-,5 The vapors from the radiator instead "of es- V caping' through the. overflow pipe as usual rise through the large tubes 6, 6, andare'agik' tated, mixed, cooled and condensed by the cool air drawn through'pertorations-7 int'o chain:

The condensate flows. back-to the body of theengine-cooling liquid through said pipes. 6, 6, and so alsodoes the condensate collecting in the cup chamber 8 through hole 8? The provision of the small tube 9 and its closed connection with the overflow pipe 7 causes the vapors to rise from the radiator intolthe condensing structure but permits It .will be observed that with this construcl I 7 tion a large part of the water or water and alcohol that evaporates as an incident of the operation of the motor is-ret-urned to the radiator thereby lessening the burden of supplying liquids to the radiator and lessening the necessity for constant caution inthe respect. Alcohol is not only'quite expensive but much'more volatile than water hence a large saving is efi'ect'ed in cold weather by the use of'the invention.

The forms of the parts can be changed without departing from the gist of the inven- 95. tion as claimed. p 1 What I claim is: r 1. A condenser for, a motor vehicle .radia-f tor system comprising'a capfa chambered 1 extension of said cap, said'extension provided 1. a
